Thanks! The only indicators of 'Mustang' on mine were the two full size 'Mach 1' decals, and the tri-bar in the front grille... oh, and the running horse on the high beam indicator and steering wheel center pad (which mine was shot and replaced with a Grant GT during the restomod process). The door sills have 'Ford' decals on them, but they fell off shortly after I applied them. Otherwise, that was it - I guess Ford was wanting the Mach 1s to stand apart from the Mustangs, and it seems to have worked somewhat since more people seem to think ALL '71-'73s are Mach 1s, and not as much Mustangs with different model variants.
My '82 GL had 2 'Ford' badges (one on the grille - which I removed - and one on the hatch lid), along with a single 'Mustang GL' badge on the other side of the hatch lid, and a single tri-bar on the horn button (that went away when I swapped for a Grant GT Challenger wheel), and a tri-bar medallion on the hood - that was it from the factory. Since it was the late '80s, and it was my first car, I went nuts at Pep Boys, getting some center hub tri-bar medallions (wheels), door handle 'Mustang' emblems, key hole scratch guards with running horses, some nice embroidered floor mats, and epoxied some tri-bar badges from my friend's '66 to the same early model fender locations on mine - along with a custom eyebrow logo and some lettering on the Dobi I-lid headlight covers (which were actually good for another 2mpg at highway speeds). When the '87s came out with the 'Mustang' logos inlaid in the quarter window glass, I cut out a pair of leftover alloy decals from something else I'd bought and placed them in the lower corners of my quarter windows. Apparently, I was a Rice Boy before it was cool, having gone to the box parts store with the crap magnet on full power, and you'd think it would be pretty gawdy by description... but my little 4-cylinder Fox-body was a cool car despite it all.
I'd learned how to do window tint, custom vinyl striping & lettering, and all sorts of other little 'detail' stuff like that, and even the guys with the other much cooler cars (like the '66 Nova II and '69 GTO also seen in the pic) had me tint their windows and do other things to their cars. And Yes, the dent came with the car, and No, I never learned how to do body work when I had that car.
